Statistical methods for assessing and predicting the economic impact of natural disasters
Abstract
The different types of evaluation of economic losses in crop from natural disaster are discussed: based on information about partial areas of crop loss; based on the concept of vulnerability; based on dynamic time series; losses of crops in agricultural plants. Predicting crop damage from natural disaster at any level performed on the basis of information on this indicator for several years. It allows to create a dynamic series to determine the trend of damage and accept the method of promising extrapolation.

Comparative analysis of stabilty of 2 varieties of springrape (Brassica napus L.) to the effect of the ions copper and zinc
Abstract
The paper is devoted to the effects of higher concentrations of salts CuSO4 and ZnSO4 on several physiological parameters of two species of plants of spring rape (Brassica napus L.) - Westar and Podmoskovny. It is established that the copper salt had on the plants of both varieties stronger effect than zinc salts. Based on these data, it is concluded that rape especially grade Podmoskovny is more effective for the removal of nutrient substrat of zinc ions than copper ions.

Morphogenesis of excretory system of rabbit's mammary gland under the influence of «E-selenium» and «Selenolin®» preparations
Abstract
The results of an experimental study of the development of female rabbits mammary gland excretory at different times of the reproductive cycle, against the background of changes in hormonal status of females and the influence of selenium are represented. It was shown, the selenium preparations have stimulating effect to mammogenesis, lactogenesis and lactopoesis. In the experimental groups (especially when «Selenolin®» was used), an increase of lactation process time comparing with control groups was observed. Despite the low «E-selenium» effectivity than «Selenolin®», its impact to mammary gland hystophysiology was uniform and gentle.

Dynamics of some indicators of morphology and biochemistry of the blood of rabbits in conditions of stress and immune correction therapy with «Ronkoleukin®» and «Gamavit» preparations
Abstract
The paper presents an analysis of some indicators of the morphology and biochemistry of the blood of rabbits in conditions of stress and immune correction therapy Ronkoleukin® and Gamavit. The data on indicators of blood hemoglobin concentration, erythrocyte count, total and agranular leukocytes, glucose content. Revealed a positive effect on the body of stress animals immunomodulators, more Gamavita.

Histologic structure of coccygeal glands quails and pigeons
Abstract
In article modern results of researches of a histological structure of coccygeal glands quails and pigeons are presented. The conducted researches confirm holocrine secretion type coccygeal glands of birds. In epithelium glandular tubules and excretory duct of gland under the morpho-functional characteristic three layers are differentiated: the first layer - germinative; the second - a layer of the cages accumulating a secret in vacuoles of cytoplasm and, the third is a layer necrobiosis and secret allocation.

Acetylcholine-acetylcholineesterasa system in piglet rectum during early period ofpostnatal ontogenesis
Abstract
It was revealed thet thehighest intensity of the age acetylcholin content changing in proximal part rectum plot of purebred and crrossbreed piglet is at the age of twenty one to thirty days, and in distal at the age of ten to twenty one days of age. Acetylcholinesterase activity is graduelly changing in proximal part rectum plot during the first to tenth days and distal during the teuth to twenty first days of age.

Interaction between cattle organism and some factors of environment
Abstract
Concerning the problem of combination of environmental and anthropogenic conditions for animal in cattle breeding the systematized approach allows to develop reasonable decision and solve the problem of interactivity between the animal organism and environment with the aim of receiving the highest stable level of productivity and high quality production, healthy animals under the combination of factors: natural (climatic) and anthropogenic (technological, technical, feeding, utilizing).
